1640s, from French catafalque (17c.), from Italian catafalco "scaffold," from Vulgar Latin *catafalicum, from Greek kata- "down" (see cata-), used in Medieval Latin with a sense of "beside, alongside" + fala "scaffolding, wooden siege tower," a word said to be of Etruscan origin. The Medieval Latin word also yielded Old French chaffaut, chafaud (Modern French échafaud) "scaffold."
